GROUP 4 METAL DIENE COMPLEXES AND ADDITION POLYMERIZATION CATALYSTS THEREFROM |
摘要 |
Novel Group 4 metal complexes containing one and only one cyclic delocalized, anionic, pi -bonded group wherein the metal is in the + 4 formal oxidation state and having a bridged ligand structure, also referred to as constrained geometry complexes and a conjugated diene divalent anionic ligand group; catalytic derivatives of such complexes including novel zwiterionic complexes; and the use thereof as catalysts for polymerizing olefins, diolefins and/or acetylenically unsaturated monomers. |
